ASSIGNORS TO THE YORK.

PREST-O-LITE COMPANY, INC., A CORPORATION OF NEW STORAGE BA'lTERY.

To'all whom it may concern: I Be it known that we, IRVINE M. NOBLE andWVALTER E. GossLINe, both citizens of use with batteries intended forthe United States, residing at Indianapolis, in the county of Marion andState of Indiana, haveinvented certain new and useful Improvements inStorage Batteries, of

exact description. I

.This invention is. an improvement instorage batteries applicablegenerally to such devices, but more especially designed .for isolatedplants such as house lighting. The chief which the following is afull,,clear, and

objects'ofthe-improvement are to produce a more-compact battery in Whichthe plates are not subject to any displacement, such as fanning orspreading, and this we .accomplish by the construction that maybedescribed in' general terms as follows.

The outside,'whic'h are usually the negative plates of battery element,are con- Y to maintain the entire element inposition structed orprovided at their lower edges and near their sides with projections orextensions containing vertical slots. Through these slots are passedflat hard rubber strips, which-span the two outside plates and which areadapted to constitute bridge sup- ,ports for the I separators.Preferably the ends of the bridge strips are made wider than-theintermediate portions or with lugs thereon so that when inserted andallowed to drop to the lower ends of the slots, the 'en-.

larged ends formshoulders which engagewith the projections on the platesandserve and prevent spreading. I I

The positive plates. may rest on the bridges or engage therewith invarious ways as, hereinafter indicated, and the ends of the bridgestrips may have soft rubber caps thereon to lessen any possible breakageof the glass battery jars from contact or shock at such points duringhandling or shipment.

improvement will be more fully set forth by reference to theaccompanyingdrawings in which:

The details and specific nature of the same at Specification of LettersPatent. Patented Aug. 2%, 192(1 Application filed August 26, 1918.Serial No. 251,359. I

Q Figs. 3, 4,5 and 6 are details of modificaby which, in theusual andwell known manner they are connected with and supported by the posts 3and 4:, as shown.

I The outside negative plates 6 at oppositesldes of their lower edgesare constructed or provided with extensions or'projections 7 whichcontain vertical slots 8.

When the plates are properly assembled and supported, bridge pieces orstrips 9, preferably of hard-rubber or other suitable insulatingmaterial, are passed through the slots in the opposite outside plates,and these I strips, as shown in Fig. 2,-are made wider at their ends,sufficiently for the purpose of the case at the lower edge only, so asto afford a lug or shoulder 10, so that when passed through the slotsthe strips will drop tobrin'g the said shoulders into engagement withthe outer surfaces of theplates, and thus efiectively prevent the entireelement from expanding or fanning out.

These bridge strips afford supports for the separators of wood or otherinsulating material 11, which are used between the plates. Theymay alsoserve to engage either or both the'intermediate positive andnegativeplates which are thus prevented from slipping apart as a result of theiroil'- center support. Finally, soft rubber caps 12 are placed over theprojecting ends of the strips to take up any possible shocks by theelement coming in contact with the walls of the jar. I

In carrying. out this invention various modified expedients may beadopted as desired, or as found necessary. For example, as shown in Fig.2, the positive plates may be provided with feet 14, which rest upon 3the top edge of the bridges- In this case the negative plates do notrest upon the bridges, the group of plates being, merely held inposition by the frictional contact of the positive plates against thebridges fastened to the outside .negative plates only.

The negative plates in this arrangement may, however, be provided withone or more feet each, or both negative and posil tive plates may eachhave one foot.

ing but one projection or stop 15,

In Fig. 3 the negative plates remaining as before, the-positive platesare provided with notched feet, the extensions of the notches extendingdownward over the bridges so as to lock the positive group in definiteposition. In Fig. 4, the positive plates are shown as provided with feethavwhich extends downward and engages but one side of the bridge strip.

In 5 the positive and negative plates have no feet but each has a pairor pairs of downwardly-extending projections or lugs 16, and in thisarrangement it is not intended that the plates should rest upon thebridges so much as that the projections or lugs should come in contactwith the sides of the bridge strip near its top. Being opposed in theiraction to each other, they thus tend to pinch the bridge and thus removeall outside strain thereon as the groups of plates tend to alinethemselves in their or on both sides of each bridge strip. It is centersof gravity.

In Fig. 6 both the positive and the inside negative plates have feetwith notches and further manifest that/ the function and not the form ofthe bridge strips and plates, in-

negative plates of which are provided with slotted projections orextensions from their lower edges, of insulating bridge strips supportedby the slots in said projections and storage battery with the group ,ofelements, the outside extending beyond the surfaceof the samesubstantially to the walls of the battery cell, and forming supports forthe intermediate positive plates and separators, the

bridge strips being formed with shoulders which engage with the outersurfaces of the projections to prevent spreading of the elements, andsoft rubber. caps applied over the ends of the bridge strips to formcushioills between the same and thevwalls of the ce 2. In a storagebattery the combination with the group of elements, the outside plateshaving projections from their lower edges, of insulated bridge stripspassing through slots in the said projections, having shoulders forengaging with the outer surfaces thereof and extending beyond theprojections to the walls of' the cell, the said strips forming supportsfor intermediate plates which have projections in their lower edges toembrace and engage with said strips, whereby fanning and spreading ofthe plates are prevented and their position in the cell maintained;

In testimony whereof we hereunto aflix our signatures. IRVINE M. NOBLE.
